I would like to know what is the maximum number of ip phone extensions that can be supported by the UC500, i have the 24user model.

From my understanding; my 24 user model, is capable to support up to MAX 24 IP PHONES. How about the number of extensions?

I am using the IP Phone 7945g, that supports 2 line keys.

Is the maximum extensions dependent on the number of line keys on an ip phone?

Plz advice

Did you try this entering the following command under telephony-service

max-dn ?

It will display maximum number of dn your system can support

There is no limit. Common sense recommend a maximum of 4.

A show ver will tell you how many user license you get.

The 24 user model gives you 28 or 30 licenses

Under telephony-service run

'max-ephone ?'

'max-dn ?'

To see the max # or ephones or DNs

You should use either 3 , 4 or 5 digit extensions depending on the size of your office and existing dialplan
